Biamp Rotel 1075 on Lsi15's for Rotel 1095 like performace?

[Pwrmx24]

I posted this in the speakers forum by accident I think it belongs in elcetronics....if anybody has some words of help that'd be great thanks...

I plan on going to listen to some amps at the store.
I have Lsi15's on the way but they don't have them at the stereo store I am going to. (I hope they don't get shipping damage by DHL from Frys).

Anyway I was hoping they would let me check out a Rotel 1075 and 1095 with my speakers at my house for a couple of hours but I seriously doubt it.

Question: For 2 channel, can I take the 1075 (120 wpc @ 8 ohms x 5) and take two channels and dedicate them to one speaker via biamping and get close to the performance of the 1095 (200 wpc @ 8 ohms x 5) ??

I will get a matching prepro for the amp and was hoping to save the $1000 diff in the 1075 and 1095 to go toward that. I understand from a previous post that the biamp on the LSi 15's only separates the tweeter. True?

I don't really know what bridging is but can you bridge a 5 ch amp to put more power to one channel?

I watch a movie at home once in a blue moon and when I do I could just reconnect for 5.1. A pain probably but I'm blamestorming to come up w/ ideas to save $$.

The 1075 is 200wpc @4ohm. Is that not enough? You can always bi-amp it if you want to get a little bit more out of the amp. I think it's only a little bit more because the Lsi were always classified as "power hungry". I fou bi-amp, the tweeter is receiving A LOT or power but that not where it's power hungry. So to anwer your question, 4 channels bi-amp to the Lsi does not equal to 2 channels of the 1095.

I have the feeling you may be satisfy with the 200wpc unless you feel that you have to have more than 200wpc for your Lsi.

The RMB1095 also sounds better then the RMB1075. It has a cleaner and deeper sound. It's also has a quieter background. It plays 4 ohm speakers more effortless.

Buy the 1095 , it's the way to go.

Agree with Dan. Just keep saving money until you have enough to get the 1095. The amps aren't going anywhere. And don't be afraid to buy used on Audiogon.

I stalked Audiogon for over a year waiting to get my prepro at a price I was willing to pay.

Wait, save and get the best 2 channel amp you can if 2-channel listening is your primary goal. Bridging amps adds distortion. Passive bi-amping does not yield as much perfomance gains unless you go to active bi-ampsing, which is adding an outboard crossover.

If you really want to go the distance, get a 1090 used on the Gon (380w/8 ohm) and you will not be want for more.
